HUGH ROBERT ROSS, OF BELFAST, IRELAND.

APPARATUS FOR CRISPINGOR FOLDING CLOTH.

SPECIFICATION forming part of Letters Patent No. 590,630, dated September 28, 1897.

Application filed October 23, 1896.

To all whom it may concern.-

Be it known that I, HUGH ROBERT Ross, a subject of the Queen of Great Britain, residing at Bloomfield, Belfast, in the county of Down, Ireland, have invented certain new and useful Improvements in Apparatus for Crisping or Folding Cloth, of which the following is a specification.

This invention relates to apparatus for what is known as crisping cloth or folding it lengthwise, and is designed to provide a machine which will take the cloth of any width from a beam or batch upon which it is wound or placed and double it evenly throughout its length into the form known as doubled or crisped cloth.

It consists, essentially, of apparatus constructed with two rows of tentering-clips or endless clip-chains placed upon the same axis or axial plane, each engaging one selvage of the cloth to draw the two selvages together while it is being doubled or creased, in conjunction with a pivoted arm or lever to crease and lay the cloth and a pair of rollers to draw the cloth forward and deliver it when folded It will be fully described with reference to the accompanying drawings.

Figure 1 is a side elevation, partly in section; Fig. l, a side elevation ofthat part of the ap-. paratus which supports the cloth-beam; Fig. 2, an end elevation with parts removed; Fig. 3, a plan; Fig. 3, a plan of Fig. 1.

The machine is constructed with suitable supporting-framing A and table B.

At one side of the machine I mount two endless clip-chains or sets of tentering-clips 0 upon the same vertical axis, the clips of one set being parallel to those of the other set and working independently each to grip one selvage of the cloth.

' The clips 0 may be of any well-known or the selvages of the cloth as it passes through the machine. These clips are connected together to form a chain to automatically seize the selvage of the cloth as it enters the machine and after carrying it forward the, required distance release it again. The clips 0 are carried forward by disks D, having suitable teeth d, and are opened by the disks E.

Serial No. 609,849. (No model.)

The disks D and E are. mounted upon vertical spindles F F and driven by gearing G.

At the same side of the machine I mount a sword-arm or lever H, which passes into the fold of the cloth and stretches it out. The sword or lever H extends across the machine and is preferably of L or approximately L shape, (though any other convenient shape may be employed.) It is pivoted at h, so that one end is free to enter between the folds of the cloth and draw the center away in a horizontal direction from the selvages, which are held by the clips 0. At the free end it is provided with a curved piece K, which bears upon the cloth.

To the other end of the sword or lever H (orin other convenient position) is connected a strong spring M to keep the free end of the lever H tight in the crease of the cloth and to allow it to yield with inequalities of widthin the cloth. The spring M is preferably placed on a rod m, pivoted to the end of the sword or lever H, and abuts against the framing A or a strong block or beam attached thereto.

The lever or sword is preferably pivoted to a movable or adjustable bracket N, secured to the fra ming'A by a screw or bolt 02, capable of being moved to and from the clips 0 to adjust the machine to take cloths of different widths.

I find it preferable to employ an arm 0 to direct the cloth into the machine, but this is not essential, especially for narrow cloth.

At the delivery end of the machine are placed a pair of geared rollers P, which draw the cloth through the machine and deliver it in the crisped or folded state.

At the receiving end of the machine are placed two rails R R, which guide the cloth into the machine.

The beam or batch of cloth S is supported in a vertical position in front of the machine. The beam is supported by two radial brackets T T, pivoted upon the pillar U. These brackets are capable of being moved around the pillar to adjust the distance of the beam of cloth S to or from the machine, according to the width of cloth, and the journals 8 of the beam S are adjustable in the slots t of the brackets T T to maintain the delivery edge of the cloth on the beam always on the sameline y 3 The brackets T T are secured in position on the pillar U by pins passing through holes it in the flanges or collars It. The positions of the journals 5 are adjusted in the slots by the screw t".

In operation the cloth is drawn oif the beam or batch S and passed into the machine between the rails R R or rollers, the selvage edges being gripped by the clips O,which each engage one selvage of the cloth. At the same time the sword or lever II straightens out the fold or crease of the cloth, which in its folded state is caught by the rollers P and thereby delivered in its crisped or doubled condition.

lVhat I claim as my invention, and desire to protect by Letters Patent, is-

1. A machine for crisping or folding cloth longitudinally, comprising two endless clipchains of t-entering-clips, placed upon the same axis or axial plane, each engaging one selvage of the cloth, and cooperating to lay the two selvages together, substantially as described.

2. A machine for crisping or folding cloth longitudinally comprising two endless chains of clips arranged on the same axis, each to engage one selvage of the cloth, and lay one selvage upon the other, a pivoted lever to enter between the folds of the cloth and straighten out the two plies as they fold together, and rollers to deliver the cloth in a foldedstate, substantially as described.

In a machine for folding cloth longitu dinally the combination with a pivoted horizontal lever II to straighten out the folds of the cloth, a spring M to hold the free end of the pivoted lever H pressed against the cloth,

' and rollers P by which the cloth is delivered from the machine, of two sets of tentering' clips placed at the same side of the machine one above the other, each to engage one selvage of the cloth and draw them together, substantially as described.

4:. In a machine for folding cloth the combination of two sets of tentering-clips working from the same vertical axis in two horizontal planes to receive and lay the edges of the cloth together, the vertical spindles F F and the disks D and E which support the chain of clips O, the horizontal pivoted lever II which passes into the fold of the cloth and stretches it out, the curved piece K on the side of the lever II which bears against the cloth the spring M which holds the free end of the lever in position the movable adjustable bracket N upon which the lever II is pivoted the guide-arm O the table I and the rollers I which draw the folded cloth forward substantially as described.

5. In a machine for folding cloth longitudinally the combination with two sets of tentering-clips placed at one side of the machine to lay the selvages together, a pivoted horizontal lever to stretch the cloth and a pair of rollers to draw the cloth forward of two radial brackets T T pivoted upon a pillar U to support the beam of cloth S, the pillar U, the journals .9 and the adjusting-screw 25 substantially as described and shown.

In testimony whereof I have signed my name to this specification in the presence of two subseribin g witnesses.

IIUGII ROBERT ROSS.
